S-DES Algorithm:-

Encryption:- Encryption algorithm takes an 8-bit block of plaintext and 10-bit key as input and produce an 8-bit block of ciphertext as output.
1. Encryption algorithm involves five functions:
1) an initial permutation function (IP)
2) a complex function (fk) which involves both substitution and permutation
3) a simple permutation function (SW) that switches two halves of data
4) the function f again
5) a permutation function that is the inverse of the initial permutation(IP-1).
2. The function fk takes as input ....etc

An improvised MOS transistor model suitable for
Geometric Program based analog circuit sizing in
sub-micron technology

A special monomial form of the device model is required by the Geometric program. This article describes the work done in identifying the sources of inaccuracy in this basic model. The strict monomial form has been relaxed. the sizing problem is solved as a series of geometric programs instead of solving it considering as single entity. a folded-cascode op-amp sizing example is used to describe the efficiency of th ....etc

Solar energy is becoming increasingly attractive as we struggle with global climate change. However, while solar energy is free, non-polluting, and inexhaustible, solar panels are fixed. As such, they can not take advantage of maximum sunlight as weather conditions and seasons change. A solar panel receives most of the sunlight when it is perpendicular to the sun's rays, but the direction of sunlight changes regularly with changing seasons and time. Currently, most solar panels are fixed, ie the solar array has a fix ....etc

c program in computer program



C Program to reverse a number :- This program reverse the number entered by the user and then prints the reversed number on the screen. For example if user enter 123 as input then 321 is printed as output. In our program we have used modulus(%) operator to obtain the digits of a number, we store the digits in an array, pow functions of math.h is used to obtain the reverse of the given number.

THE EFFECT OF PAIRS IN PROGRAM DESIGN TASKS
In this project efficiency of pairs in program design tasks is identified by using pair programming concept. Pair programming involves two developers simultaneously collaborating with each other on the same programming task to design and code a solution. Algorithm design and its implementation are normally merged and it provides feedback to enhance the design. Previous controlled pair programming experiments did not explore the efficacy of pairs against individuals in program design-related tasks. Va ....etc
